The fallout from Tyga's 'Make It Nasty' video is still haunting the rapper. A fourth woman has slapped the Young Money rhymer with a major lawsuit behind the X-rated clip.

According to TMZ, Allison Brown filed a lawsuit alleging that her breasts were revealed in the video despite being promised that her nipples wouldn't be exposed.

The model also claims that during the shoot, which took place in November 2011, she was fondled by someone in a yellow rabbit costume and when she tried to get away from the rabbit another man on the set grabbed her breasts.

Brown also claims she was supplied with plenty of alcohol despite being underage -- she was 20 years old at the time -- and no one asking her for identification.

As we previously reported, two other models are suing the YMCMB rapper for allowing their breasts be exposed in the explicit version of his 'Make It Nasty' clip.

The video vixens, Elizabeth Velasquez and Azia Davies, are seeking 20 million in damages -- that's $10 million per set of boobs. Whoa! Now that's a lot of racks!
